AI Technical Summary
Because the airflow direction inside the heat pump is the same as the direction of the duct extension, the heating effect inside the airflow is uneven, resulting in inconsistent air temperature discharged by the heat pump.
Design a heat exchange device for a heat pump. The device uses an air duct installed inside a box and an electric heating wire wound around it. The fan is tilted by a tilting frame and a drive assembly, which causes the airflow to blow towards the inner wall of the air duct. The tilting posture of the fan is controlled by a bending rod and a drive assembly to ensure that the airflow is heated evenly.
This ensures that every area of the airflow can come into contact with the warmer inner wall of the duct, reducing the inconsistency in the temperature of the heat pump exhaust airflow and improving the temperature uniformity of the heat pump exhaust airflow.

[0001] The utility model relates to the field of heat pumps, and specifically refers to a heat exchange device for a heat pump. Background Art
[0002] A heat pump is a device that heats the relatively cold external air to form a heat-carrying air flow and transports it out. Generally, a heat exchange of a heat pump uses a duct with a fan installed at one end, and electric heating components are arranged around the duct to heat the air flow when it passes through the duct.
[0003] The direction of the air flow transported by the fan is the same as the extension direction of the duct. However, due to the design of the duct heating structure, the temperature at the inner wall near the edge of the duct is necessarily higher than that at the center of the duct. Then, if the air flow velocity in the duct is relatively large, the air at the center of the duct is not sufficiently heated, which will result in inconsistent temperature and heat in the air discharged by the heat pump. Therefore, a heat exchange device for a heat pump is provided. Content of the Utility Model
[0004] I. Technical Problems to be Solved
[0005] The technical problem to be solved by the utility model is that due to the same direction of the air flow in the heat pump and the extension direction of the duct, there are differences in the internal heat reception effect of the air flow.
[0006] II. Technical Solutions
[0007] To solve the above technical problems, the technical solution provided by the utility model is: a heat exchange device for a heat pump, including a box body, a duct is installed in the box body, and electric heating wires are installed around the duct in a winding manner outside the box body.
[0008] An air inlet end and an air outlet end are connected to both ends of the duct of the box body. A fan is installed in the air inlet end of the box body, and a tilting frame is installed on the box body, which can control the tilt of the fan and prompt the air flow input into the duct to blow towards the inner wall of the duct.
[0009] Further, the tilting frame includes a bottom plate installed on the air inlet end of the box body and a carrier plate for installing the fan. Three bending rods are uniformly installed between the edge of the carrier plate and the bottom plate, which can change their own bending degree to change the tilting state of the carrier plate.
[0010] Further, the bending rod includes a first rod rotatably connected to the bottom plate and a second rod rotatably connected to the carrier plate. The ends of the first rod and the second rod are rotatably connected to each other. A plurality of driving components are installed on the bottom plate to drive the rotation of the first rod to change the bending degree of the bending rod.
[0011] Further, the driving component includes a transmission shaft rotatably disposed on one side of the bottom plate. A motor is installed on the bottom plate and is in transmission cooperation with the transmission shaft. A rotating rod is installed at the end of the transmission shaft, and a guide rod is rotatably connected to the end of the rotating rod. A support shaft is connected to the first support rod, and a driving block rotatably connected to the support shaft is connected to the end of the guide rod.
[0012] Further, a telescopic cylinder for cooperating with the inclined movement of the fan is jointly installed between the bottom plate and the carrier plate.
[0013] III. Beneficial Effects
[0014] Compared with the prior art, the present utility model has the following advantages: The heat pump heat exchange device is configured such that the fan can be inclined. By rotating the fan and its carrier plate, the air flow is forced to hit the inner wall of the air duct. In this way, every area of the air flow can have the opportunity to contact the relatively hot inner wall of the air duct, thereby greatly reducing the occurrence of inconsistent temperatures inside the air flow discharged by the heat pump.

[0022] The following further describes the present utility model in detail with reference to the accompanying drawings.
[0023] To solve the above technical problems, the technical solution provided by the present utility model is as follows: A heat exchange device for a heat pump, in combination with the attached Figure 1-2 , includes a box body 1, and an air duct 2 is installed inside the box body 1. In combination with the attached Figure 3 , the box body 1 is installed with an electric heating wire 3 around the periphery of the air duct 2 in a winding manner;
[0024] An air inlet end 5 and an air outlet end 4 are connected to both ends of the box body 1 where the air duct 2 is located. A fan 16 is installed inside the box body 1 at the air inlet end 5. In combination with the attached Figure 3-4 , a tilting frame capable of controlling the inclination of the fan 16 and prompting the air flow input into the air duct 2 to blow towards the inner wall of the air duct 2 is installed on the box body 1. A telescopic cylinder 17 for cooperating with the tilting movement of the fan 16 is commonly installed between the bottom plate 6 and the carrier plate 7;
[0025] Using a heating component mainly composed of the electric heating wire 3 to raise the temperature of the environment inside the air duct 2, and then using the fan 16 to introduce external air flow into the air duct 2 from the air inlet end 5 of the air duct 2. After the air flow is heated, it is extruded from the air outlet end 4, and finally hot air is obtained. The tilting frame carrying the fan 16 changes the orientation of the fan 16, making the air flow it transmits blow towards a certain place on the inner wall of the air duct 2, so that each part of the air flow can directly contact the area near the relatively high-temperature inner wall of the air duct 2, thereby making the overall temperature of the discharged hot air relatively uniform;
[0026] In combination with the attached Figure 5-6 , the tilting frame includes a bottom plate 6 installed on the air inlet end 5 of the box body 1 and a carrier plate 7 carrying the installation of the fan 16. Three bending rods that change their own bending degree to prompt the change of the tilting state of the carrier plate 7 are commonly and evenly installed between the edges of the carrier plate 7 and the bottom plate 6. The bending rod includes a first support rod 8 rotatably connected to the bottom plate 6 respectively and a second support rod 9 rotatably connected to the carrier plate 7. The ends of the first support rod 8 and the second support rod 9 are rotatably connected to each other;
[0027] Multiple driving components for driving the rotation of the first support rod 8 to change the bending degree of the bending rod are installed on the bottom plate 6. The driving component includes a transmission shaft 14 rotating on one side of the bottom plate 6. A motor 15 that is in transmission cooperation with the transmission shaft 14 is installed on the bottom plate 6. A rotating rod 13 is installed at the end of the transmission shaft 14. A guide rod 12 is rotatably connected to the end of the rotating rod 13. A support shaft 10 is connected to the first support rod 8. A driving block 11 that is rotatably connected to the support shaft 10 is connected to the end of the guide rod 12;
[0028] Under the operation of motor 15, transmission shaft 14 carries rotating rod 13 to rotate to a certain extent, which causes guide rod 12 to push and pull the rotating support rod 8 to a certain extent, thereby changing the degree of bending between support rod 8 and support rod 9. Ultimately, one end of the carrier plate 7 tilts on one side of the base plate 6. The three motors 15 on the base plate 6 operate in opposition to each other, but also cooperate with each other. After each end of the carrier plate 7 tilts to any degree, the tilt state of the carrier plate 7 and the fan 16 as a whole is also diverse. Therefore, the target position of the airflow blowing towards the inner wall of the duct 2 also has a wide variety of choices. Under this constant change between multiple destinations, the inner wall of the duct 2 near the fan 16 has a relatively equal opportunity to provide heating for the airflow.
[0029] In a specific implementation of this utility model, when the heat pump is running, the fan 16 and the three motors 15 on the base plate 6 are running continuously. Due to the operation of the three motors 15 and the control of the drive components, the fan 16 switches back and forth in various tilting postures. The tilted fan 16 guides the external airflow to collide with the inner wall of the air duct 2, which has a higher temperature. The airflow is fully and evenly heated and then squeezed out from the air outlet 4 of the air duct 2 by the air that subsequently enters the air duct 2.
[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
